Magiclantern for 5d4 and 5ds

[qspqww]

I'm wondering if there is a useable raw video recording for 5D4 or 5Ds because I'm going to buy a second-hand camera.

Neither of these cams support raw video.

Fine, I will buy a 5d3

It's a good cam!  Has the highest recording rates of any supported ML cam, and should be a lot cheaper to find than 5D4.  The 5D4 does have nicer AF, but, no real ML support.  Since you want raw video, probably the right choice.  If 5D4 gets ML support, you can always upgrade then, and the prices should be lower.
